  • METHOD FOR ENCODING AND/OR DECODING IMAGES ON MACROBLOCK LEVEL USING INTRA-PREDICTION
    Publication number: 20140205008
    Abstract: Conventional intra-prediction uses pixels from left and upper neighbour blocks to predict a macroblock (MB). Thus, the MBs must be sequentially processed, since reconstructed left and upper MBs must be available for prediction. In an improved method for encoding Intra predicted MBs, a MB is encoded in two steps: first, a first portion of the MB is encoded independently, without references outside the MB. Pixels of the first portion can be Intra predicted using DC mode. Then, the first portion is reconstructed. The remaining pixels of the MB, being a second portion, are intra predicted from the reconstructed pixels of the first portion and then reconstructed. The first portion comprises at least one column or one row of pixels of the MB. The encoding is applied to at least two Intra predicted MBs per slice, or per picture if no slices are used.

    Patent number: 8787561
    Abstract: A technique for detecting in-band signaling tones in a communication system includes performing a first adaptation of an adaptive filter of an echo canceller in response to detection of a far-end harmonic signal. In this case, the adaptive filter provides an echo estimation signal. The technique also includes subtracting the echo estimation signal from a near-end signal that includes one or more in-band signaling tones to provide an error signal. The technique further includes detecting, using a tone detector, the one or more in-band signaling tones in the error signal.

  • Computing device and image correction method
    Patent number: 8781207
    Abstract: A computing device reads a reference image and a real-time of a printed circuit board (PCB), determines feature points and feature information of the feature points in the reference image; and creates two 1×N matrices based on the feature points. Furthermore, a mapping matrix is determined based on the two 1×N matrices. The device determines matching points in the real-time image based on coordinates of base points in the reference image and the mapping matrix, determines a matching region the real-time image based on the matching points, and determines an angle between the matching region and an X-axis of a coordinate system. If the angle does not equal zero, the device determines that the real-time is tilted, and corrects the real-time image to obtain a corrected image by taking a center of the real-time image as a turning pivot to rotate the real-time image until the angle equals zero.
